Hi! I think I can get these to ship as a "large letter" so the shipping to US would be GBP £9.50 with tracking and signature (it's also the same price with tracking but without the signature), or £5.00 with no tracking, just standard delivery. The delivery aim is 5-7 working days for all those options, and standard does still come with a receipt with your address as proof of postage but it doesn't have any way to track the package on it's way. Thank you for your question, I hope this is helpful!
